MEANS FOR DETAINING OR RELEASING TOP LIFTS IN HEL-NAILING MACHINES.

SPECIFICATION forming part of Letters Patent No. 707,143, dated August 19, 1902.

To all whom t may concern.: plate A' constitutes -a support for the back Be it known that I, EDWIN A. LOUGEE, ofgage and other operative parts.` In accord- Haverhill, -in the county of Essex and State ance with my invention the stud e has been l olf/Massachusetts, have invented an Improveprolonged above the top of4 the plate, and I 5 ment inMeansforDetainingorReleasing Tophave mounted upon it a leverf, having its 55 Lifts in' Heel-Nailing Machines, of whichpthe short end f recessed to constitute a guide following description, in connection with the to receive loosely a link f2, the long end of y accompanying` drawings, .is a specification, said lever (see Fig. l) `being provided with like letters on the drawings representing like a suitable roller f3. The stud e has secured zo parts` upon it above said levera toe'g, and-above 6o In heel-nailing machines it has been cus the toe the .stud is surrounded by a spring tomary to apply a heel-holder and a top-lift g', one end of which is connected with said s holder to a plate which is swung so that it toe, While the other end acts against a part y occupies at times a proper position to place a ofv the lever f, said spring normally, acting I 5 heel above the nail-block, andthe heel havto keep oneside of said lever against a stop 65 y ing been attached the plate is moved to place h, extended from a block h', applied to the l a top lift under the heel, so that atthe next stud e,said block being recessed, as shown, rise of the usual die-bed spindle 'the top to receive and surround the springg. To the lift will be spanked onto the protruding nails stud e above the block h I apply a washer m i 2o extending somewhat from theftread end of and above it anut m.

the heel. The top lift is usually thin, and The link f2 is connected byasuitable pin/rt in the lateral movement of the plate holding with the short arm of a lever n', pivoted at fn?, itl the top lift is liable to be disturbed or to said lever having some teeth, as at n3, which escape from'its holding devices, and to over-v 'engage with other teeth n4 of a second lever come this diculty I have added to the back a5, pivoted at n6,said teeth causing said levers 75 gage of the top-lift holder a detaining and reto move toward and `from each other in unileasing device, it serving to detain and then sonwhenthelever n' is movedby orthrough f at the proper time to release the" top lift. the link f2. 1

Figurel is a top vieWof a plate having a .The forked or back gage c to receive the 3o heel and top-lift holder, the latter being prorear end of the top lift lies close.l to and just 8o vided with my improvement, Fig. 2 is aparabove a part of the plate A, so thatathe top tial under side View of Fig. 1. Fig. 3 is a lift laid upon the plate may have itsrounded detail in side elevation of part of a lever inrear edge pushed into the saidfork,the breaststrumental in actuating the top-lift detaining gage c' keeping it in the fork.- and releasing device, said lever' having a The levers4 n and ns constitute what Ihave 85 guide. Fig. 4 is a section in the line Fig. 1. designated as a top-liftdetaining andI rerIhe plate A and forked gage et to` receive leasing device,and normallythey occupythe the rounded rear end of the heel, the breastl position shown by full lines in Figs. 1 and 4.- gage 0. to act on the breast of the heel, the that is, they overhang the innerledges of the 40 forked gage c to receive the roundedend of fork c, so that the rounded end of the top lift 9o the top lift, the breast-gage c' to act upon the is pushed, as it might be considered,into a breast of the top lift, theA said breast-gages sort'of a box; but just as'the toplift is to be being controlled by suitable springs, as d d', spanked upon the heel the roller f Smeets rsome the said plate vhaving a lix'ed stud e, which fixed lor movable part of the'heeling-machine serves as a pivot, and aroller e', which is andispushed laterallyintotheposition shown 95 acted upon when it is desired to turn the plate by dotted lines, such movementofthe lever f A to place either the heel or the top lift above resulting in separating the top lift detainer or in line with the vertical movement of the into its dotted-line position, Fig. 1, so that die-bed spindle, are and may be all substanthe edges of said detainer no longer overlap a l 5o tially as usual in heel-nailing machines. The portion ofthe top 1ift,-leaving it freeto be roo pressed firmly against the heel-seat end of the heel, and as the die-bed spindle is again lowered the top lift holder and detainer retire from the heel, and in its iinal descent the lever f under the control of the spring g is moved into its full-line position, thus causing the inner edges of the lever constituting the top-lift detainer to again cross and overlap somewhat the inner edges of the fork or back gage of the top-lift holder.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A back gage and a support therefor, combined with a detainer and means to actuate it that said detainer may 4at times overlap part of the space of the back gage and at other times be moved to uncover said space.

2. A back gage to receive the rear end ofa top lift, andasupport for said gage, combined with a detainer to overlap the edge of the back gage and a top lift therein, and means to open said detainer to effect the release of a Top lift.

3. A top-lift back gage, a support therefor, and levers operatively connected together and constituting a top-lift detainer, combined with means to actuate said levers in unison to release the top lift.

4. A top-lift back gage, a support for said gage, and two levers pivoted on said back gage and operatively connected together to constitute a top-lift detainer, combined with means to actuate one of said levers, causing both of said levers to be moved in unison toward and from each other.

5. In a machine of the class described, a toplift carrier, means for positioning a top lift on the carrier, a detainer extending over the top lift, and means to Withdraw said detainer before the top lift is spanked onto a heel.

6. A pivoted plate, a forked back gage for a top lift, a breast-gage acting against the breast of a top lift, means moving with said plate and operating automatically to retain the top lift temporarily in the back gage, and means to turn the top-lift-retaining means to release the top lift when it is to be spanked on an attached heel.

7. The plate A provided with means for holding a heel, and means having a back gage for holding a top lift; a lever pivoted above said plate and provided with a guide; and a link in said guide; combined With a top-lift detaining and releasing mechanism operatively connected With said link, said mechanism coperating with the back gage ofthe top-lift holder, To at times overlap andhold, and to then release the top lift.

8. A back gage, and a support therefor, combined With a detainer located above and acting to partially cover the space in said back gage, a device connected with said de tainer and means to actuate said device 'to move said detainer in a horizontal plane to uncover the space in the back gage.

In testimony whereof I have signed my name to this specication in the presence of two subscribing Witnesses.
